lt will he observed that the ridges 18 fall short. or the forward or leading end of the end bar l0 on which they are made, or, in vother words, this leading` end is recessed in lront oi' he ridges, and this then leaves pon tions of this end har extending forwardly beyond The ridges so rhat if Jdie hnckle he used upon a thin strap, this :forwardly eX- lending portion of the leading end of the end har 10 of the sliding tongue will have a. tend ency to crowd or bend the lliin material underneath the adjacent edge of the front end loar 3 of the frame and render che ridges doubly elieient in griviping the fabric be- Vii-iveen iiheinselves, their supporting 'har and *die adjacenl' edge o'lf die freni end har 3 of *die freine.

A s already indicated, the upstanding ridges are interposed as ehsiacles lo the escape of the sirop end ld when once it is engaged between ihe sliding tongue and the adjacent iframe, and they thus operate hy virjlgue er the ,hiet that they put as niany erimps in the strap as there are ridges. rdinarily two parallel ridges are sufiicient.

The srujiporting grooves or guideivays formed by the iniroverted 'llanges en the side liars of 'the ranie are eti widili to take easily ille side hars e'l che tongue, and so as to perni; the Longue lo nieve 'iherein lengthwise wiihenl; cramping. lhe flair straighty edged el freier ol Idie sil the longue Ipeeulirnly iiis lhe longue 'lor iree movement in said grooves or guideivays.

The depression or the cross-har 5 permits, as it were, of the counter nliing of the looped end of the sl:` ap l5 Within the'diinensions of the buckle, so as to avoid any undue humping of the fastened end 14.

By the construction described'a very slim buckle is produced without in the least im pairing its efliciency as a gripping or huckling agent, and moreover the huelde may he economically constructed and assembled.

What I claim is tl.. A, sliding tongue louelde, comprising a iframe, and a sliding longue supported therein, said sliding tongue having a strapgripping end har provided with, upstanding ridges running iore and aft and said end har recessed in front el the ridges and thus leaving the leading end Vof the end har eX- lending forwardly of the ridges, and said ridges andthe forwardly extended end har coperating `with the lraine to crimp the strap and grip it between the tongue and lrarne 2. A sliding tongue buckle, having a frame with a front end bar, a sliding tongue snpporred in said frame and having an end har provided wiih fore and aft upstanding ridgesg said end har recessed in front of said ridg so as to leave its lea-ding end extending 'forwardly beyond sind ridges toward. the

'front end har of the frame, the tongue being supported in the freine below the level of the lraines front end har, so that `the for Wurdly extended leading end of the end. har of the sliding iongue is adapted to crowd a and under the adjal'hin slrap end against;
